一般描述

焦碳酸二乙酯（DEPC）是一种用于灭活RNase酶并对水分和pH敏感的化学制品。在155℃时它在水溶液中可分解成乙醇和二氧化碳。DEPC对能将其分解成氨基甲酸乙酯这种潜在致癌物的氨也很敏感。

应用

焦碳酸二乙酯已在PCR反应中用于处理去离子水，以降低了RNA被RNase降解的风险。它还可以用于斑点印迹杂交，以稀释分离自不同微生物的总RNA。
蛋白中His及Tyr残基的修饰试剂。用于dsDNA结构破坏的稳健探针，可与完全或部分未堆叠的碱基发生反应。

生化/生理作用

DEPC是一种潜在的核酸酶抑制剂。0.1%的DEPC溶液用于灭活RNase。
它可以剂量和时间依赖的方式抑制兰尼碱与骨骼肌中兰尼碱/ Ca2+受体通道的结合，并提高SR囊泡的Ca2+通透性。
在溶液中浓度约为 0.1% (v/v) 时可使 RNase 失活，从而防止 RNA 被降解。

  1. What is the stability of Product D5758, Diethyl pyrocarbonate, at room temperature?

    The material is stable at room temperature as long as it is protected from moisture.  We do recommend 2-8 °C for its storage.

  2. How can I tell if Product D5758, Diethyl pyrocarbonate, has degraded?

    DEPC breaks down to ethanol and carbon dioxide.  The carbon dioxide builds up pressure inside the bottle; when opened, it will degas and/or bubble out of the bottle.

  3. What buffers can I use with Product D5758, Diethyl pyrocarbonate (DEPC)?

    DEPC reacts with amines, thiols, and alcohols.  Any buffer that contains an amine, e.g.., Trizma, should not be used.  View this information on the product information sheet (under Documents, above.

  4. What type of container should I use to handle Product D5758, Diethyl pyrocarbonate (DEPC)?

    Glassware is preferable since some plastics, e.g.., polycarbonate, are known to react with DEPC.

  5. Why is stirring or shaking necessary when making RNAse-free water for use with Product D5758, Diethyl pyrocarbonate?

    DEPC is not very soluble in water. Stirring and/or shaking is necessary to suspend DEPC in water.

  6. What is the best way to use Product D5758, Diethyl pyrocarbonate, to inactivate RNAse?

    Add DEPC directly to the water to yield a 0.1 % solution.  Shake vigorously and allow to set overnight at room temperature with the lid loose or incubated for 2 hours at 37 °C.  The solution is then autoclaved 15 minutes for each liter.

  7. Which document(s) contains shelf-life or expiration date information for a given product?

    If available for a given product, the recommended re-test date or the expiration date can be found on the Certificate of Analysis.

  8. How do I get lot-specific information or a Certificate of Analysis?

    The lot specific COA document can be found by entering the lot number above under the "Documents" section.

  9. How do I find price and availability?

    There are several ways to find pricing and availability for our products. Once you log onto our website, you will find the price and availability displayed on the product detail page. You can contact any of our Customer Sales and Service offices to receive a quote.  USA customers:  1-800-325-3010 or view local office numbers.

Water for Nuclease-sensitive Molecular Biology Studies

Nuclease-free water (or PCR water) is needed in molecular biology to avoid sample degradation during PCR, sequencing, etc. Ultrafiltration provides a quicker, safer, and more sustainable alternative to DEPC treatment when preparing RNase-free and DNase-free water.
